Room temperature control Fig. 9
A suitable room temperature controller or a DDC
outstation with 0-10 VDC output 2-wire (terminals 1
and 3) connected. With a common supply voltage of
24 V, note that terminal 1 is also ground for the con-
trol signal.
Override control: With 24 VDC at terminal 3, the
volume flow rate set at the Vmax potentiometer is
started.
Initial commissioning
Before you start commissioning:

Ensure that the device or unit has been cor-
rectly fixed and connected to the ducting.

Ensure that the devices or units as well as the
ventilation system are clean and that there are
no residual matter and foreign objects.

Important: If there is a risk that the controller
could be subject to mechanical impact during
operation, protect it accordingly; protection has
to be provided by others.
For commissioning see also VDI 6022, part 1 – 'Hy-
giene requirements for ventilation and air-condi-
tioning systems and units'.
